Description
Technical field
The present invention relates to the field of textile mills' technology and relate to according to independently a kind of method of Patent right requirement and a kind of device separately.This method and apparatus is used for the production of staple line, and this staple line is made up of synthetic fiber at least in part, and this is the staple fibre of making from synthetic or natural polymer with the synthetic technology method.
Background technology
Situation according to this area, spinning process is applied to the production from the line of staple fibre, this is the spinning process from cotton or wool fibre, and the small-sized fiber band of one of them rove or make with extra care and is submitted to then an appropriate methodology that is used for twisting apparatus that line forms or other compactings turbulent flow (turbulence) or the connection of fiber (for example by) by stretching.Line refining before forming also can be by being that single-stranded fiber obtains with the fibre strand shredding.The fibrous material that is provided for spinning process is normally taken out a bundle in advance, if necessary be cleaned and/or mixed (admixing) and step (combing, combing, stretching etc.) through preparing, rely on fibrous material, brought into the structure that is suitable for specific spinning process and is used for specific final products, brought therein into fiber usually only by adhesion or the coherent structure of frictional force and they vertically have preferential, a parallel direction therein.
At short fiber material is under the situation of synthetic fiber, the fiber bundle is produced in such a way, promptly for example by from the elementary spinning process of the extrusion way of spinnerets, produce similar endless long filament, these long filaments are stretched and fix to be used for macromolecular arrangement and to be merged into multifilament to form the multiply silk, by cutting or tearing (conversion), thin slice and these thin slices of producing staple fibre from the multiply silk are pressed into bundle.Then the further processing of synthetic material basically with the preliminary treatment of summarizing above, refining and sequence consensus that line forms.
So the staple fibre of preparation depends on and how the multiply silk is separated, and has whole basically equal lengths (rectangular fiber distribution of lengths Pareto diagram) or resembles natural fabric similarly, has variable-length in a zone.
The line production process that is used for synthetic fiber of the application that causes the fiber bundle that summarizes above is very complicated.Yet it has such advantage, and promptly the synthetic fiber bundle can be processed in identical with the natural fabric bundle basically mode.In other words that means the identical auxiliary machine processing of these the two kinds available textile mills of bundle.Therefore, line can be from synthetic fiber by substantially the same textile mills' processing, and these synthetic fiber are to come from staple fibre, come from natural fabric and also can come from the mixture of these two kinds of fibers especially.
A kind of simple more method that is used for from the staple line production of synthetic fiber is so-called directly (sliver to yarn spinning) spinning.According to this method, the similar endless long filament of producing by the main spinning process for example extrude and stretch and so on is combined to most multiply silks that form again.The multiply silk be guided one therein long filament be torn or cut and the fiber that obtains therein forms thing by stretching by refining device.The fiber that obtains by this way forms thing and is directly caused into line formation then.These methods with usefulness above-mentioned/compare by fiber bundle method of operating, have such advantage, and promptly they are obviously simpler.Being arranged in parallel within the conversion process of long filament is held basically in the multiply silk, promptly the staple fibre that obtains from the conversion of long filament seldom need be for line forms parallelization.Fibre length and the fiber length distribution in the direct spinning process depend on that the length that is provided for long filament reduces and the setting and/or the configuration of the device made from extra care (converter) of fiber skein.
Along with the line in the direct spinning method forms substantially the same with based in the spinning method of fiber bundle, be arranged in refining the having to that line forms the upstream differently to be arranged the described refining length minimizing of also having to comprise long filament.Therefore, with traditional spinning method contrast that is used for from the production of the line of staple fibre, the direct spinning method need be equipped with spinning frame especially.And, demonstrate the line of producing by the direct spinning method and trend towards periodically fluctuating and can not satisfy high-quality demand.The direct spinning method can't be taken the easy production of blended yarn, the i.e. line of for example being made up of the mixture of synthetic fiber and natural fabric into account.
Summary of the invention
Present task of the present invention provides the production that a kind of method and a kind of device are used for staple line, and this staple line is made up of synthetic fiber at least in part.The production that foundation this method and apparatus of the present invention can be easy to satisfy their application and also can adapt to the high quality standards line.According to this method and apparatus of the present invention but also allow, expensively transform, from short fibre mixture particularly from the production of the line of the mixture of natural and synthetic fiber.
This task is by this method and utilize this device to solve, and this method and apparatus is defined in claims.
With foundation method of the present invention, the long filament of producing in preliminary spinning process is stacked into the plane and is stacked.This plane is stacked and is pressed into spinning net (spinning combination) then.This spinning net is then by from vertically splitting into the little net of many spinning net, then reduced from length by this separating analogous endless long filament, and therefore obtain the staple fibre product.Each narrow spinning net is caused the spinning unit of spinning frame and is made with extra care and be submitted to then a linear apparatus for converting (twisting apparatus or other pressure settings that is fit to) at spinning unit.The line that online then formation device obtains is drawn back from spinning unit.
Preferably, in the zone that the spinning net is produced, storage and supply unit are the shapes of thin, soft plain-weave silk fabric cotton yarn tape or spinning net, and it is used for the actual line product as base product then.Can realize separating the product and the line products (secondary textile mills) of spinning net or thin, soft plain-weave silk fabric cotton yarn tape (elementary textile mills) by this method.
Be preferably in stack before elongate filaments and if necessary so fix it, promptly arrange big molecule at least in part and guarantee within this is arranged at direction filament.This long filament that stretches at least in part can at random or with given pattern be stacked basically.For the compacting of the plane layer that makes the long filament that becoming spinning net, know that in fact diverse ways is available.For example the long filament of thermoplastic polymer quilt is by suppressing between the flat pressurizing unit of heating respectively, and promptly they are pressed by the method with heat.
Suppress mixing (for example cold-adhesion or the press polish) realization that also can pass through jointing material (synthesizing compacting) or pass through to push or pass through turbulent flow (mechanical compaction) or drawing method.
The fibroreticulate separation that enters narrow spinning net is for example to realize with the machine cuts device.By cutting, fibre end obtains (other positions at narrow spinning net do not have this fibre end) at the longitudinal edge of narrow spinning net.In the separation process of spinning net, should consider that fiber can not be pulled away from out narrow band and fibre end can not combine.Be included in the length of the staple fibre in the narrow spinning net and the stacking kind that distribution of lengths directly relies on long filament in the width of narrow spinning net and the net that spins.The spinning guipure is narrow more, and fiber is just short more; It is neat more that long filament is stacked, and the length of fiber is consistent more.The arrangement of the staple fibre in the narrow spinning net also relies on the kind of the delayer of long filament.Because all fibres end all is positioned at the longitudinal edge of narrow spinning net, the height of fiber is arranged can not be longitudinally.The degree of narrow spinning net fineness is by the density of spinning net and the width decision of narrow band.
For making with extra care of narrow spinning net, before the online formation, described guipure relies on predetermined line and forms twist especially and rely on that the line that will produce is stretched by a traction unit or decompose under a help of decomposing roller, and this point is in that to be used for traditional short fiber material known.If necessary will be suppressed with the device that is fit to for the refining narrow spinning net that provides.The compacting of spinning web frame is partly decomposed at least in refining process.If if the sufficiently firm or clamping point of this compacting distance than the compound weak point of fiber, also the stretching by narrow spinning net makes the big molecule in the fiber more parallel.
Line forms by the open-end spinning of for example ring spinning, centrifugal spinning, cap spinning spindle, friction spun yarn, opening or open-end spinning and takes place, and conventional apparatus is very suitable to these.The stretching to greatest extent that is used for the fiber that macromolecule adjusts to greatest extent also can also realize down by online environment, and line is stretched and is fixed with hot method in for example online formation of this environment and between reeling.
The compacting that the plane long filament is stacked is with a kind of like this mode of selected usefulness, and promptly it is partly decomposed at least in the subtractive process of narrow spinning net.Have only real traction that this mode can realize that fiber is rectangular and in the subtractive process of the stretching by narrow spinning net fiber the high depth of parallelism and when by decomposing handling respectively fully fiber when refining.In fact firm connection between the long filament that obtains in pressing process needs high tractive force, yet, when making with extra care, except fibre parallelization, also consider tensile fiber and/or can use the fixing molecule adjustment of hot method, under for example online environment by stretching.
For production from the blended yarn of different synthetic fiber, different spinning nets gathered and lamination (compound, plying) or simultaneously different narrow spinning nets caused secondary spinning process, wherein different synthetic fiber are for example for having produced from different materials in elementary spinning process and having stacked good long filament basically simultaneously.Production in order to spin similarly from the mixing of synthetic fiber and natural fabric, net separately (net and web for example spin) is gathered and lamination, so obtain a hybrid network and obtain to mix little net from this net, perhaps, in order to obtain narrow spinning net, natural fabric is rectangular to be caused spinning process in addition.
Description of drawings
The method according to this invention and device are done more detailed description with reference to the accompanying drawings, wherein show:
Three kinds of narrow spinning nets and attached fibre length Pareto diagram (minimal fibre length is as the function of pars fibrosa) that vertical separation of Fig. 1-3 spinning net is produced;
The effect of the feature of the narrow spinning net of Fig. 4 on fibre length, Fiber Distribution and stacking quantity;
Fig. 5 is according to the schematic description of the step of method of the present invention;
A kind of schematically device of expression of Fig. 6 is used for carrying out according to method of the present invention.
The specific embodiment
Fig. 1-3 shows at the schematic section according to different narrow spinning nets in the method for the present invention, and this narrow spinning net is submitted to subtractive process and is used for the line formation that line produces.The fibre length Pareto diagram that is attached to narrow band separately is indicated on the right of narrow net section.The longitudinal edge of narrow band is represented with chain-dotted line.
This narrow spinning net is to make by vertical separation of spinning net, and described spinning net is made up of many approximate endless long filaments.Long filament that should be approximate endless separates by vertical separation of spinning net, makes the termination of staple fibre all be positioned at the next door of the longitudinal edge of narrow band.Staple fibre in narrow spinning net, depend on the compacting type of spinning net, preferably by with the method for heat or can mechanically engage synthetically or also, then heat and the synthetic fixing and mechanical connection that typically intersected as fiber by model of being connected as the fiber turbulent flow.
Narrow spinning net according to Fig. 1 derives from the spinning net, and long filament is fully freely stacked in the spinning net.For the arrangement and their length difference of this reason fiber seldom consistent.Fiber to very different fibre lengths will be expected.
Narrow spinning net according to Fig. 2 derives from the spinning net, and long filament is stacked by strictly arranging good order in spinning net, for example with net vertically compare at both direction.A kind of like this net that spins can be produced during elementary spinning network process is moved laterally to the throughput direction path of stacking long filament because of being arranged in of spinning head, for example, and circularly back and forth.Thereby the speed as the relative action that is obtained between spinning plate and transport must be the same high by the speed that discharges from elementary spinning apparatus with long filament.The Fiber Distribution of the narrow spinning net of making from a kind of like this net that spins is rectangle (all fibres is same length basically).
Narrow spinning net according to Fig. 3 is made by the spinning net, and long filament is stacked by only arranging good order roughly in the spinning net.For a kind of like this production of the net that spins, spinning plate is moved laterally to the throughput direction of spinning net, so the movement velocity and the transporting velocity that are produced by the motion of spinning head are lower from the speed that elementary spinning apparatus discharges than long filament.
In narrow spinning net, so a fiber length distribution occurs, this fiber length distribution is located between the fiber length distribution according to the narrow band of Fig. 1 and 2.
From Fig. 1 to Fig. 3, clearly having proved can be by the spinning net the line produced according to method of the present invention of production control in fiber length distribution, particularly by described mode therein long filament stacked.
The line which feature that Fig. 4 schematically shows narrow spinning net is made to synthetic material with from synthetic material is influential, and/or which feature by narrow spinning net makes synthetic material or the feature of the line made from synthetic material is affected.
Further describe as top, fibre length and Fiber Distribution are stacked (strictly to arrange good or mode freely) via fiber and are adjusted by the width of narrow band.Stack fineness (quality of per unit length in narrow spinning net), it is become the line fineness by stretching or decomposing then, the product of the per unit zone weight of netting by spinning basically and the width of narrow band produce, and are adjusted at the width place that sets in advance of narrow band by this per unit zone weight.
Fig. 5 schematically shows the step according to method of the present invention, and this method is used for the production of staple line, and this staple line is made up of synthetic fiber at least in part.
In elementary spinning step, similar endless long filament 1 is produced from synthetic material and is stretched so that increase strength according to qualifications.Described stretching can be implemented and influence in this case the arrangement of macromolecular The cream of the crop under the help of air.In addition, described stretching can under the help of draw-off godet, be affected and influence a kind of basically fully or molecule adjustment to greatest extent.Thereafter for fear of the contraction during temperature increase after a while, filamentary material preferably also is submitted to the bearing of a heat in this case.
In the pressing step of following after long filament is stacked step, the layer 2 of long filament is pressed into spinning net 3.Described compacting symbolically is described among Fig. 5 by the projecting point of long filament institute infall.For the thermoplastic filament material, the described compacting method of handy heat is finished, and promptly long filament is pushed down under the environment of plastics and therefore welding or be bonded together each other each other.Should consider that when selecting temperature and pressure the fiber during making with extra care connects and must be decomposed at least in part.In addition for machinery or fluid power plant entanglement long filament or by press polish or cold bonding compacting long filament stack can increase adhesive (for example this) by the type of cleaning or other suitable modes are removed to be used for the long filament compacting layer.
Before compacting or also can be thereafter, other short fiber material also can be added to long filament and stack 2, for example with the cotton fiber of the form of carded web.
In separating step, narrow spinning net 4 by such as among Fig. 1-3 vertical separation of detailed description and spinning net 3 described in these figure produced.The staple fibre end that produces from long filament all is positioned at the longitudinal edge of narrow spinning net.Fiber alignment is to a kind of order of arranging from a kind of freedom; Consider that narrow strip length fiber is mainly by uneven arrangement.The spinning net can be under rolled-up situation separated entering in the narrow spinning net, perhaps under the situation of tension, for example utilize a kind of rotating knife by the grinding and cutting mode, for example motion by cutting blade, by scissors, tear, water sprays cutting, laser cutting or the like.
Narrow spinning net 4 is made with extra care in purification step by the fiber rectangular 5 that stretches or decomposition (opening) becomes to be fit to spin then.So the fiber that obtains in pressing step connects to become and separates at least in part or take apart and staple fibre is adjusted in its direction of motion most ofly.
In the online formation step, spinnable fiber rectangular 5 is twisted or turn then, so fiber rectangular 5 forms line 6, described line 6 is wrapped on the yarn package 7.Replace twisting, the drawing method of Shi Heing (for example by turbulent flow or bonding) also can be provided in addition.If necessary, in order to arrange fully at the macromolecular of machine direction, between online formation and the winding step, described line 6 can also be stretched and/or be fixing fixing so that molecule is adjusted.
Above-mentioned foundation this method of the present invention can be used as the direct spinning method and realize, this direct spinning method is carried out substantially continuously from elementary spinning step to secondary spinning step.Yet, at least up to now, operate with very different output speeds and can not move down in same management and roof (management and roof) usually because be used for the primary and secondary spinning apparatus, so preferably separately be used for primary and secondary spinning step region method.This point is because spinning net 3 is reeled on the spinning net volume tubes 10 or stacked in the container and transported by this way and recognize.The first step in secondary spinning zone is a separating step then; Because narrow spinning net 4 is separated from spinning net 3.This can be by spinning net 3 unwinding and instant cutting or be divided into disk by the net volume tube 10 that will spin and take place, narrow spinning net 4 is then by from these disk unwindings.On the other hand, the separation of spinning net 3 also can realize in main spinning zone.The narrow spinning net 4 that obtains from separating step twisted in then the narrow roll coil of strip adorn 11 or the narrow band reel 12 of beam of a loom type (warp-beam-type) on and be transported to secondary spinning step zone by this way.
